Add support for virtual methods(vm) to the generator.
* parser/gapi2xml.pl: Generate a class_struct element with
all members of the class structure. Dump the first (instance)
parameter for signal and vm elements. Bump up parser version.
* generator/GObjectVM.cs: Added. Support for GObject virtual methods.
* generator/DefaultSignalHandler.cs: Signal specific part of vm
generation.
* generator/InterfaceVM.cs: New class for interface vms.
* generator/ObjectBase.cs: Parse the class struct.

* atk/Atk.metadata: switch Value methods to ref params since atk
actually checks for initialized values instead of just treating it
like uninitialized memory. Makes for uglier API, but avoids crashes
in unfortunate memory content scenarios.
svn path=/trunk/gtk-sharp/; revision=110382
* atk/Atk.metadata: markup all the Ref* methods to indicate owned refs.
* generator/ReturnValue.cs: Add owned object ToNative handling.
* generator/VirtualMethod.cs: Split ToNative call from managed method
invocation to avoid duplicate calls in null checking scenarios.
* glib/Object.cs: add OwnedHandle property for use by language binding
code which needs to pass owned refs to native methods.
